Abstract

A surgical device includes a forceps and a blade. The forceps includes a first working jaw and a second working jaw. The blade extends along a longitudinal axis and includes a notched section. The blade is located between the first working jaw and the second working jaw. A first therapy current can be connected to the first working jaw, the second working jaw, or both so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated. While the tissue is gripped between the first working jaw and the second working jaw, the blade is moveable along its longitudinal axis so that the tissue is cut with the notched section without repositioning the first working jaw, the second working jaw, or both.

First claim

The invention claimed is:

1. Surgical forceps for grasping and cutting tissue, the surgical forceps comprising:
a first working jaw;
a second working jaw; and
a blade extending along a longitudinal axis and located between the first working jaw and the second working jaw, the blade including:
a notched section including a proximal edge, a distal edge, and an upper edge extending between the proximal edge and the distal edge, the blade moveable along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the proximal edge or the distal edge of the notched section without repositioning the first working law, the second working jaw, or both, and the blade rotatable between a first rotated position and a second rotated position.

2. The surgical forceps of claim 1 , wherein in the first rotated position, the upper edge faces either the first working jaw or the second working jaw, and in the second rotated position the upper edge faces a direction between the first working jaw and the second working jaw.

3. The surgical forceps of claim 1 , wherein the blade is rotatable about the longitudinal axis between the first rotated position and the second rotated position.

4. The surgical forceps of claim 1 , wherein the first working jaw and the second working jaw define a blade track, the blade is located within the blade track, and the blade is rotatable within the blade track.

5. The surgical forceps of claim 1 , wherein the blade is rotatable between the first rotated position and the second rotated position when the first working jaw and the second working jaw are in a closed position, an open position, or a position therebetween.

6. The surgical forceps of claim 5 , wherein the blade is rotatable between the first rotated position and the second rotated position when blade is being advanced or retracted.

7. The surgical forceps of claim 6 , wherein the blade is a blade electrode that is connected to a second therapy current.

8. The surgical forceps of claim 5 , wherein the blade is coupled to a rotation wheel.

9. The surgical forceps of claim 8 , wherein the blade is coupled to the rotation wheel by a support rod.

10. The surgical forceps of claim 7 , wherein a distal end of the blade electrode is moveable beyond a distal-most end of the forceps so that the distal end of the blade electrode functions as an electrosurgical blade.

11. Surgical forceps for grasping and cutting tissue, the surgical forceps comprising:
a gripping assembly comprising:
a first working jaw, and
a second working jaw; and

a blade extending along a longitudinal axis and located between the first working jaw and the second working jaw, the blade including:
a notched section including a proximal edge, a distal edge, and an upper edge extending between the proximal edge and the distal edge, the blade moveable along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the proximal edge or the distal edge of the notched section without repositioning the first working law, the second working jaw, or both, and the blade rotatable between a first rotated position and a second rotated position independently of the gripping assembly.

12. The surgical forceps of claim 11 , wherein the first working jaw and the second working jaw define a blade track, the blade located within the blade track, and the blade rotatable within the blade track.

13. The surgical forceps of claim 11 , wherein the blade is rotatable between the first rotated position and the second rotated position when the first working jaw and the second working jaw are in a closed position, an open position, or a position therebetween.

14. The surgical forceps of claim 13 , wherein the blade is rotatable between the first rotated position and the second rotated position when the blade is being advanced or retracted.

15. The surgical forceps of claim 11 , wherein at least one of the proximal edge and the distal edge is both generally linear and generally perpendicular to the longitudinal axis.

16. The surgical forceps of claim 11 , wherein the first working jaw, the second working jaw, or both is connected to a first therapy current so that tissue gripped between the first working jaw and the second working jaw and within the notched section can be coagulated with the first therapy current.

17. The surgical forceps of claim 16 , wherein the blade is a blade electrode that is connected to a second therapy current.

18. Surgical forceps for grasping and cutting tissue, the surgical forceps comprising:
a gripping assembly comprising:
a first working jaw, and
a second working jaw, the first working jaw and the second working jaw together defining a blade track; and

a blade extending along a longitudinal axis and located in the blade track between the first working jaw and the second working jaw, the blade including:
a notched section including a proximal edge, a distal edge, and an upper edge extending between the proximal edge and the distal edge, the blade moveable along the longitudinal axis while the tissue is gripped between the first working jaw and the second working jaw so that the tissue is cut with the proximal edge or the distal edge of the notched section without repositioning the first working law, the second working jaw, or both, and the blade rotatable between a first rotated position and a second rotated position independently of the gripping assembly.

19. The surgical forceps of claim 18 , wherein the blade is coupled to a rotation wheel.

20. The surgical forceps of claim 19 , wherein the blade is coupled to the rotation wheel by a support rod.

21. The surgical forceps of claim 18 , wherein the blade is rotatable between the first rotated position and the second rotated position when the first working jaw and the second working jaw are in a closed position, an open position, or a position therebetween.
